## What frequency of radio waves is harmful?

The most restrictive limits on whole-body exposure are in the frequency range of 30-300 MHz where the human body absorbs RF energy most efficiently when the whole body is exposed.

## Can we see radio waves?

What Is the Electromagnetic Spectrum? The electromagnetic spectrum describes all of the kinds of light, including those the human eye cannot see. … Other types of light include radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays — all of which are imperceptible to human eyes.30 мая 2019 г.

## How do I figure out frequency?

Divide the wavelength into the velocity to calculate the frequency, expressed as described above as the number of cycles per second, or Hertz – written “Hz.” For example, a water wave with a wavelength of 1 foot traveling at a speed of 4 inches per second has a frequency of 1/3 feet/second divided by 1 foot = . 33 Hz.

## Which wave has highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

RF radiation has lower energy than some other types of non-ionizing radiation, like visible light and infrared, but it has higher energy than extremely low-frequency (ELF) radiation. If RF radiation is absorbed by the body in large enough amounts, it can produce heat. This can lead to burns and body tissue damage.
